| Abstract: | An actively mode-locked fiber ring laser with SOAs Is presented.The materal gain profile,spatial distribution of carriers and the broad-band spontaneous noise emission are considered in the model.The result of theoretical study and numerical simulations reveals that 7.5 ps stable mode-locked pulse trains at repetition rate of 20 GHz can be obtained,and the pulse trains are constant over a 40 nm tuning range. |
| |
| Keywords: | semiconductor optical amplifier (SOA) mode-locked pulse trains repetition rate cross-gain modulation (XGM)) |
